100 Katy Trail Ln,
Saint Charles,
MO
63303
Saint Charles sits along the Missouri River about 20 miles northwest of downtown St. Louis, carrying the distinction of being the first Missouri state capital and one of the oldest cities west of the Mississippi. Founded in 1769 by French-Canadian fur trader Louis Blanchette, the city has grown into St. Charles County's seat while holding onto a strong sense of history that shapes daily life here. Lindenwood University anchors the city's educational presence, and major employers along the Boeing corridor and throughout the St. Louis metro draw residents who want suburban ease with metropolitan access.
Neighborhoods vary noticeably across the city's 24 square miles. The Historic Main Street and Frenchtown District offer walkable streets lined with brick storefronts, boutiques, and riverfront gathering spots. New Town at St.
